title: Management of unstable angina pectoris.
abstract: The diagnosis of unstable angina may be confirmed if an ECG taken during an episode of pain demonstrates ST-segment changes that resolve when the pain is relieved. An intra-aortic balloon device should be used in the rare patient who has recurrent episodes of ischemia despite maximum drug therapy. Coronary angiography should be performed as soon as possible after the device is inserted.
